2.6 Operational safety and particular hazards

Please observe the safety notes and the warnings listed here and in other chapters of

this product documentation to reduce the possibility of risks to health and avoid dan‐

gerous situations.

CAUTION

Optical radiation: Laser class 1

The accessible radiation does not pose a danger when viewed directly for up to 100

seconds. It may pose a danger to the eyes and skin in the event of incorrect use.

■

Do not open the housing. Opening the housing may increase the level of risk.

■

Current national regulations regarding laser protection must be observed.

WARNING

Electrical voltage!

Electrical voltage can cause severe injury or death.

■

Work on electrical systems must only be performed by qualified electricians.

■

ments in the operating instructions.

■

National and regional regulations must be complied with.

■

Safety requirements relating to work on electrical systems must be complied with.

WARNING

Risk of injury and damage caused by potential equalization currents!

Improper grounding can lead to dangerous equipotential bonding currents, which may

3.2 Product characteristics

The distance sensor consists of the optics, a sender/receiver unit and an evaluation

unit.

The device emits invisible, infrared laser beam pulses. The receiver receives the light

reflected from a measuring object (=echo). The evaluation electronics determines the

distance between the sensor and the measuring object using time-of-flight measure‐

ment.

The device supports two measuring modes.

•

Axial object tracking: Measuring object moves along the laser beam.

•

Lateral entry of the object: Measuring object moves perpendicular to the laser

beam.

Parameter presettings simplify device configuration for the respective measuring mode.

The detected object distance or the object speed (configurable) is transmitted via the

serial interface (switchable: RS-422 / SSI) or via Ethernet (TCP/IP). The analog signal

output (analog output) converts the distance value into a 4 mA … 20 mA current output

signal proportional to the distance. Digital switching outputs (digital outputs) can be

used to monitor when parameterized thresholds for the distance values have been

reached. The “Distance to the object” and “Window” switching functions are supported

for doing so. In addition, the achievement of configurable switching limits for the speed

of the measuring object can be monitored via digital outputs.

A visible alignment laser facilitates alignment of the device with the measuring object.

The measurement technology is designed for indoor and outdoor applications. For such

applications, the device must be protected from environmental factors, "Mounting

instructions", page 31. The protective housing, available as an option, can be used for

this purpose.

Measured distance values can be visualized and parameter settings can be made

using the graphical touch-display. Alternatively, the device can be configured via the

SOPAS ET user interface (PC) (via Ethernet).

Measurement cycle time

Increasing the measurement cycle time causes a rise in sensor detectability. A mea‐

sured value can thus be created from very low signal strengths.

In product variant DT1000, the scalability of the range results from this: the longer the

set measurement cycle time, the larger the range of the sensor, see figure 30,

page 98.

For more information on the measurement cycle time, see "Defining the measurement

cycle time", page 54.

Rain and snow filter

The measurement certainty with precipitation can be increased using the connectible

rain and snow filter.

For more information on the rain and snow filter, see "Configuring the rain and snow

filter", page 55.

Distance averaging filter

The distance averaging filter carries out a moving averaging method of the distance

value.

For more information on the distance averaging filter, see "Configuring the distance

averaging filter", page 56.

Fog filter

The measurement certainty with fog can be increased using the connectible fog filter,

"Activating/deactivating the fog filter", page 56.

Kalman filter

The Kalman filter filters the distance and speed value based on a mathematical status

model.

For more information about the Kalman filter: see "Activating/deactivating the Kalman

filter", page 57.see "Activating/deactivating the Kalman filter", page 57.

Speed filter

The speed filter carries out a moving averaging method of the speed value.

For more information about the speed filter: see "Configuring the speed filter",

page 57.see "Configuring the speed filter", page 57.

3.7.2 SSI (synchronous serial interface)

The SSI interface makes possible serial data transmission of the distance value or of

the distance value combined with the status information. Clock and data are trans‐

ferred over the interface. The data is transferred upon request from the control system.

For this purpose, the connected control unit applies a pulse sequence to the receiving

input of the measuring device. At each positive pulse edge, a data bit is pushed onto

the measuring device’s transmission line. This starts with the highest-value bit. There is

a pause of at least 30 µs between two pulse sequences. The cycle time and transmis‐

sion rate can be adjusted in wide limits on the control side. The bit pulse is between

70 kHz and 500 kHz and is dependent on the length of cable, see "Wiring notes",

page 42.

Depending on the set SSI coding ("Defining SSI coding", page 75), the SSI telegram is structured according to the

following tables. For more information on the SSI status bits, see table 33, page 93.

3.7.3 RS-422 interface

The serial interface makes it possible to read out the measured values and other

defined operating data and transmit parameter data to the device. All data is transmit‐

ted as ASCII characters. The syntax of the communication protocol corresponds with

the specifications of the SICK SOPAS CoLa A protocol, "Commands", page 22 .

As an option, the device can be configured so that distance values as well as selected

combined data is output in a continuous data stream (see table 11, page 21) or out‐

put on request. Two different protocol types are available for continuous output: “CRLF”

and “STX/ETX”. This syntax of this continuous data is based on the DL100 and

DME5000 SICK products.

The factory presetting of the Dx1000 is:

•

Protocol type: CRLF

•

Output of measured values: on request

•

Baud rate: 115K2, 8n1 with a resolution of 1 mm

3.7.3.1 Protocol types and data for continuous output

Depending on the selected protocol type, the device transmits a continuous data

stream, as shown below: The data fields have the length specified in table 11 and are

filled out with leading zeros if necessary.

The ASCII characters of the number values such as the distance value are coded in

decimals. An exception is the status double word, whose ASCII characters are coded as

hexadecimals.
